vTHREAD SPINNING AND TWISTING MACHINE;

Application led December 13, 1,926. Serialk No. 154,577.

This invention relates to machines for use in the spinning and twisting of thread, and aims to provide such a machine that embodies all the broad principles of construction and operation of the textile spinning and twisting mechanism set out in my United States Letters Patent N o. 1,569,831, las well asv the speciiic principles of construction and operation of a iiyer and saddle device shown and described in certain copending applications tiled December i3, 1926, Serial No. 154575 and tiled December 13, 1926, Serial No. 154,576, respectively.

A main object of the invention is to provide such a machine that is equipped with a plurality of vertically spaced longitudinal decks of' spinning and twisting units, each deck consisting of two series of units at opposite sides of the machine, all' of which units are operated by a single, centrally disposed belt drive, the relation of the belt with respect to the unit being such that the spindles of the units are rotated in'a similar direction regardless of the direction of travel of the belt runs. By reason of this relation between the belt and spindles a positive drive of allof the unit spindles is secured.

A further object resides in the provision of such a machine wherein but a. single thread take up mechanism is required for the multiple series of spinning and twisting units at each side of the machine, such take up being in relatively great spaced relation with their complementary series of units thus increasing the area of the thread spinning and twisting action, it being well known that such action is performed en tirely between the thread delivery bobbin and the take ott' spool of the take up mechanism.

The invention further aims, to provide a manually and automatically controlled belt compensating mechanism at opposite ends of the machine so that unusual slack may be taken up manually, while-normal slack will be automatically compensated for with versed for acting y upon the belt, during operation thereof in different direct-ions;

lt is a still further object to provide means complementary to each spinning and twisting unit whereby the operation of any one of the units may be cut out without inter-v fering with the other units for obviously permitting of the replenishing of the delivery thread, the removal or replacement of the unit saddle, or the reconnection of the thread with the take ott' should the thread become broken. Thefcut outk mechanismof each unit is such that the spindle and its iiyer in stopped position will besuch as to permity ofV the proper disposition of the ihread through the spindle and through the yer.

An additional object resides in the provision of gradually increasing-sizes of spindle drive pulleys at the let off end of the drive belt so that these spindles will be positively operated and the driving action of the belt at the letoff end thereby saved.

Other objects will become apparent as the nature of the invention is better understood, the same comprising the novel form, combination, and arrangement of parts hereinafter more fully described. shown in the accompanying drawing and claimed. n f.

Figure l() is a perspective of one ot the unit spindles and its coinplcmentary tlyer.

Figure ll is a persia ective olf the stop arm end ot' one ot'r the cut out devices, one ot' which is complementary to each spinning and twistingl unit.

Figure l2 is a diagrannnatic View ot the unit spindles together with the central belt drive therefor. disclosing the spaced and staggered positioning ot the unit spindles projecting through opposite sides ot the unit decks and for disclosing the gradually increasing size or area oli' the spindle pulleys toward the let off side oi' the belt so that: the driving power ot the belt at its let oil side will not be wasted.

Figure 13 is a fragmentary diagranmiatic View similar to Figure l? showing the posi tioning ol the gradually increasing sizes of spindle pulleys toward the let ott end ot the belt when the direction olI movement of tho belt is the reverse from that disclosed in Figure l2, both Figures l2 and 13 disclosing the position ot the automatic compensator' during the operation of the belt in rercrse direction.

Now having particular reference to the drawings, my novel textile spinning and twisting machine includes a trame structure generally but not specifically disclosed in the drawings. Said frame consists broadly of end suliporting standards out?, at opposite sides otwhich are vertically extending strip like metallic hars GG, the central portions of which are on a true vertical plane as disclosed in Figure :2, while the opposite ends thereoit converge in 'ardly for attachment at their lower ends to said standards 5 5 and for the purpose ot supporting at their upper ends a double take up mechanism indicated generally by the reference character 7, sce Figures l and 2, said take up mechanism being ol conventional construction. Extending longitudinally between the end standards 5 5 is a pair of spaced parallel decks ot' spinning and twisting units 8-8, the lower deck being preferably supported at its opposite ends by the end standards 5--5 while the upper deck is suspended from the take up mechanism 7. This take up mechanisin is in spaced parallel relation with said decks as clearly disclosed in both Figures 'l and 2. Fach deck oi' spinning and twisting unit is of identical construction and consequently a description ol" one will suflce for both.

Each deck consists of a pair ol; laterally spaced longitudinallyy extending and paral lel itat-like rails 9-9 interconnected at their upper and lower edges by spacing blocks l0, said spacing blocksl at the upper and lower edges oll said rails being in staggered rela tion as clearly disclosed in .Figure -l. Joue naled through registering openings in said rails 99 adjacent the upper and lower edges thereot are transversely extending spinning and twisting` unit spindles ll, the hollow thread receiving ends, ol said spindles at the upper edges of the rails fl-ll ol' said deck extending through the rail at one side of the machine.V while such ends ol the lower spindles project through the other rail at the opposite side ot the deck, sce lf`igures 2 and il. Keyed to all ot .said spindles 1l within the rails 9--9 are belt pulleys l1! lormed at their opposite ends with circular llanges lil-lil for the purpose ol preventing any longitudinal morement ol the spindles by r xason olf their contact with the rails 9--9 as in the cross sectional riew, Figure il. ,Xt the inner end of the portion of cach spindle ll that projects through the adjacent rail tl there is rigidly mounted a tlycr unit lfl prcl erablj though not necessarily of the con struction shown and described in my copending application, Serial No. 1541.575, tiled llecembcr 13, 1926.

The innermost llange 1 3 olZ each spindle pulley l2 is Yformed at its edge with a notch l5 that is in direct lrmgitudinal alignment with the vertical thread `supl'iortiing wire ll of said flyer 14, see Figure lo.

Fmthermtne. the projecting end ot each spindle l1 is formed with the usual pair ot spaced circmnl'ercntial channels Vltlmlt) lor the purpose ot supliorting the delivery hohA bin carrying saddles` li' in such a manner as to prevent longitudinal mort-ment ol the saddles with resilect to the spindles. ',I`hcsc saddles l may be ol the general construeA tion shown herein, but are preferably of the constructitin shown and t'le:-cribcd in another of my copending applications. Ferial No. lstfiiti tiled December lfl. lElQt.

Secured to the outer sides ot the vertical portions ol the l'rame bars' tS-t are guard rails 1S. those at; opposite sides of the machine frame being directlyv in l'ront of the projecting ends oll the spindles il at that particular side ol' the machine. seo Figure 2. Complementary to each spinning and twist ing unit ot the pair ot' declt's 8-Sl al both sides thereof are pigl tails l) upon the inner sides Ot the guard rails 18. each pig tail bcing in substantially horizontal alignment liu with its respective spindle, see again Figurei2.

As clearly shown and described in my Patent No. 1,569,831 and as suggested herein, the thread from each delivery bobbin 17 is arranged wit-hin. the hollow end of its re s ective spindle 11 and thenceV extracted t `rough an opening 11f in the spindle directly in front of its flyer 14s. The thread is thence extended upwardly and passed through the pig tail at the upper end of the flyer wirel 14. From this point the thread is led through the adjacent pig tail '19 upon the guard rail i3 for that particular seriesk of spinning and twisting units. After passing through the guard rail pig tail the thread is then extended upwardly toits respective spool of the double take up mechanism 7, which take up mechanism consists of two series of spools at oppositeI sides of the machine frame, each series including spools of a number equivalent to the number' of the spinning and twisting units at that particular side of the machine, see Figure 1.

F orV facilitating the proper extension of the thread strands from the lower series of spinning andv twisting units at opposite sides of the machine, the uppermost guard rails 18-18 are provided at their outer surfaces with pig tails 20, the threads being led from the pig tails 19 of the lower guard rail outwardly between the guard rails at opposite sides of the machine and then through the pig tails at the upper rails, and 'from there to their respective spools ofthe ldouble take up mechanism. VBy reason of the relatively great distance between the take up 1nechanism and the decks of spinning and twisting units, particularly those ofthe lower deck, a great spinning area is provided for the reason that, as previously stated, the twisting action occurs between the point of take off from the delivery bobbin to the receiving spool of the take up mechanism.

In carrying` out the principle of operation of allof they units simultaneously, and this by reason of a single mechanism there is provided an electric motor 21, see Figure 1 disposed preferably between the end stainlards 5 one cnd of the arma-ture shaft thereof being provided' with a small sprocket gear 22 over which is trained an endless sprocket chain 23. Mounted within sup` porting brackets at the outer side of the adjacent end standard 5v is a stub shaft 2d provided with a larger sprocketv gear 2.5, and a large pulley wheel 26, Said sprocket chain 23 is also trained over said larger sprocket wheel 25 for the purpose of drivl ing the belt pulley carrying shaft 24T. Trained over this belt pulley 26 is an end less belt 27, the runs of which extend upwardly for engagement over a small and vlarge pulley wheel 28 and 2.9 respectively mounted at vthe end of the frame and slightly beneath the pair of spindle unit carrying .decks 8 8. As clearly disclosed in Figures 2, 3', d, 7, 8, 12, and 13, the upper and lower runs of thisA belt are extended longitudinally between the rails 9-9 of the respec# tive decks 8-8, whi-le said runs are arranged between and have frictional contact with the spindle pulleys 12 at the upper and lower edges of the rail of the decks so asy to `positively drive all the spindles simultaneously and in a similar direction regardless of the direction of travel of the belt. Located abovey the main drive pulley 26 of the belt power mechanism is an automatic belt slack compensator 30. This compensator consists of a. T-shaped arm 31, one end of the cross member of which is pivoted to the shaft supporting the small frame attached belt pulley 2S, while mounted uponcthe opposite end of said cross member iS a pulley 32. Then the belt 27 is traveling in the direc# tion of the arrows in Figure 12, the. arm will be so arranged'that its associated pulley 32 will contact the outer surface of the outer belt stretcl'i or runs, and pull inwardly thereon by reason of a coil spring 33. co'n-v nected at its opposite ends to the cross member directly in back of the pulley 32' and to the` adjacent end standard, sce Figures 1 and 12. lVhen the belt is operatingin a reverse direction, as indicated by the arrow in Figure 13 the T-shaped arm 31 will be swung inwardly uponV its pivot4 so that its associated pulley 32 will frictioually engage the inner run of thebelt by reason of the same coil spring interconnecting the end of the central member of the arm, and the supporting bracket for the pulley `and sprocket gear carrying shaft'2-l.

This automatic compensator takes care of the normal slack in the belt 27, while provided for thepurpose of compensating for unusual slack in the belt there is provided .at the oppositeend of the machine frame, a manually adjustable compensator designated generally by thereference character 3a. This compensator consists of a pair of transversely aligned spaced L-shaped brackets 355-35,

see Figures 5 and 6 that vare anchored to the adjacent end of 4the machine frame directly between the spaced decks 8-8 and at opposides sides of the power belt 27. The horizontal portions of these brackets 35-35 are formed at their inner surfaces with longitudinal slots 36 within which are guided the opposite edges of a flat horizontally extending plate 37, the outer end of which is bifurcatcd as at 33 to permit of they attachment of a large. belt pulley 39 to saidplate 37 betweenits furcations, and over which is trained said belt 27. The opposite edges of the plate 37 are formed with longitudinally spaced notches fl() for receivingy the ends of spring fingers li l0 anchored to the ends of the brackets 'for obviously maintaining the helt pulley carrying plate 37 in adjusted extended position. By releasing the spring lingers l1-l1. the helt pulley carrying" plate 3i' may be pulled outwardly to the desired extent for applying the proper tension to the power belt 27.

In order that the operation oi any predetermined one et the spinning and twisting units may he eut out, there is provided a stop mechanism complementary to each unit. Each ot said stop devices consists ot an elongated rod il-2. the inner end ot which is joui naled through registerinen openings in. the rails fl-) oi' the particular deck 8. The rod 4Q of the stop mechanism tor a particular unit is journaled through openings in the rails directly ahoye or beneath the spindle of the next adjacent unit as clearly dis closed in Figures "i and rl`he outer end oi the rod 42 extends through an openingr in the adjacent `guard rail lll. while the ex treme outer end thereof projet-tin;n through said guard rail is provided with a rie-ht angular arcuate shaped turning handle lil Figures l and Q. llieidly mounted or formed upon the end ol the har 42 directly inwardly 01'E the adjacent deck rail i) is a circular head 14, Fig. ll, 'from the surface of which tangentially extends an elongated har-like arm l5 that normally extends upwardly in an inclined manner in a direction toward the spindle ot the particular unit the operation of which is to he cnt out hy reason ot the particular stop device. The extreme outer end of the arm i5 is lient inwardly7 at right angles to provide a stop lug 46 for engagement within the notch l5 of the pulley flange 13 of that particular spinning' and twistingr unit. The inner surface of the head il is formed integraliv at its periphery with a laterally exten-ding' lirar 4T ot segmental formation as disclosed in Figure 1l. Surrounding the rod 42 between the head il and the remote decl; rail f) is an expansihle coil springT 48, Fig. 9, that lwill lanse the head let or lug 117 to lirictionally engage the inner surface of the adjacent decl: rail 9. Obviously. when the stop arm ot the particular unit is in elevated position as in Figures 4 and il the segmental lucr -iT is in hach oi` the adjacent guard rail il and maintained in such position hy reason ot the cxpansihle springY ln order to swing* the Stop arm 'from a spindle stop position as disclosed in Figures 'i' and 8 to a spindle released positionY as disclosed in Figures 4 and 9 it is necessary for the operator of the machine to pull slightly outwardly upon the rod 42 against the action of the coil. sprint! 3S so as to diseniace the plane under surface of the luf; 4T from the upper edge of the adjacent deck rail 9. ln actual practice, the operator iirst breaks the rotation of any desired spindle hy grasping; the same with his lingers. The particular operatingr rod i2 ot that spindles cnt out mechanism is then so turned as to swing the stop arm 45 in the direction of the spindle so that: the end Zit', oli the arm will engage within the notch l5 ot the pulley disposed upon the particular ,spindle heineY stopped. lmmediately upon the engagement ol the stop lue' Alt' ol the particular arm within the notch i5. the lue; il ot the har head fifi will he toi-ced orcr the, upper udire ot the adjacent decl: rail Si hy the. expansion of the spring fiel and conserpicntly they rod AiQ as well as the arm 45 will he locked in spindle rttnipinf.,r position.

In order to employ to the greatest extent possihlc the power of the heli at the talte oil side ot the heit. he it l'roin the pulley 2f) when the teelt mores in the direction oi" the arrows in lin'urc l2 or troni the pulley QS when the direction ot travel ot the helt is as indicated hy the arrow in Figure lil l proride pulleys lil' for the spindles ll, preicrahly 'tour in numlier and ot gradually increasing diameter toward the let oil side of the heit :s in Figures 'l2 and lfl. Ot course the particular spindles with which said increased sizes ot pulleys are associated will not rotate at the, .same rate oli speed as the other spindles. hut nevertheless the power ot the hell: at the take otl side will he utilized to a certain degree for the production ot a product: diiiferent in character from that produced where the pulleys are of eren diameter. ln other words the thread acted upon hy the tirer unit in connection with the pulleys 0'l`V uniform diameter will he given a certain numher ot twists per jncdetermiucd length. while the threads acted upon hy the flyer unit in connection with the pulleys of larger diameter will he `Qiyen a less nnmhcr oil twists per predetermined length.

The .specific operation and construction ot the inyention will he readily apparent to those skilled in the art when consideringr the accompanying drawings in association with the present specification. and eren though l hare herein shown and descrihed the inyeution as consistingr ot certain detail struc tural elements. it is nfwertheless to hc understood that minor changes may hc made therein without atl'ectincr the .spirit and .scope ot the appended claims.
